a friendly hug from nature.
Breathing: We need air to breathe. When we
breathe in, our lungs take in the oxygen from the
air, and that helps our body stay alive.
1.
Wind: Air makes wind. It can be a gentle breeze or
a strong wind. Wind can help kites fly and move
leaves and branches on trees.
2.
Weather: Air is part of the weather. It can be
sunny, rainy, or windy. Air helps make clouds and
rain.

Uses of Air
We breathe in air to stay alive, and our bodies need oxygen from
the air.
1.
When we hang wet clothes outside, the air helps dry them by
taking away the wetness.
2.
Wind, which is moving air, helps lift kites up into the sky when we
fly them.
3.
Blowing air into soap bubbles with our breath makes them float
and fly around.
4.
Fans and air conditioners use air to cool us down when it's hot. 5.
Balloons get filled with air to make them big and float, which is
so much fun!
